The brain is comprised of billions of brain cells, a vast network of synapses and neurons transmitting electronic impulses like many stars in an infinite universe. A crucial support system … Continue Reading New role identified for astrocytes in brain processing.
Stuttering is a neurodevelopmental disorder characterized by pauses and repeated sounds or words, which disrupt the normal flow of speech, causing great embarrassment for some sufferers. For 1 in 4 … Continue Reading Brain cell involved in stuttering identified.
Glial cells are immune cells found in the brain not directly involved in synaptic interactions or electrical signaling, although their supportive functions are known to play a crucial role in … Continue Reading Study identifies new key role for astrocytes in memory and learning.
The control of breathing is essential for life. Without an adequate response to increased carbon dioxide levels, people can suffer from breathing disturbances, sickness, and panic; in worst-case scenarios, it … Continue Reading Novel brainstem model show how the brain controls breathing.
Delayed deterioration of neurological function after ischemia stroke is a well-documented clinical problem. However, minimal studies exist pertaining to spinal cord blood flow and blood-spinal cord barrier (BSCB) integrity with … Continue Reading Study maps how a stroke damages the blood-spinal cord barrier.
The hippocampus is a critical structure for encoding of novel experiences. A particularly compelling puzzle is how the hippocampus encodes new information in the presence of interference from past memories. … Continue Reading Neuroimaging shows how the brain switches from past to present memory mode.
Whenever a person learns something new or is affected by their experiences it’s because synapses, the connections between neurons in the brain, have changed. Sometimes new synapses are made, and … Continue Reading Study shows how astrocytes help control synapse strength and plasticity.
When the blood-brain barrier (BBB) is breached the brain becomes vulnerable to infection and injury. Therefore, it’s imperative that the openings in the BBB are resealed quickly. This most frequently … Continue Reading Researchers identify new role for microglia in blood-brain barrier maintainence.
Astrocytes are star-shaped glial cells in the brain and spinal cord. They perform many functions, including biochemical support of endothelial cells that form the blood–brain barrier, provision of nutrients to … Continue Reading Researchers purify and grow human astrocytes-in-a-dish for the first time ever.
In comparison to other organs, the human brain has the highest energy requirements. The supply of energy for nerve cells and the particular role of lactic acid (lactate) has been … Continue Reading Study confirms 20 year-old hypothesis on the brain using lactate for energy.
A glioma is a type of tumour that starts in the brain or spine. It is called a glioma because it arises from glial cells. The most common site of … Continue Reading First ever study shows how astrocytes help to spread glioma.
A star-shaped brain cell called an astrocyte appears to help keep blood pressure and blood flow inside the brain on a healthy, even keel, a new study from researchers at … Continue Reading Study shows astrocytes maintain blood pressure and blood flow in the brain.
The mission of neural stem cells located in the hippocampus, one of the main regions of the brain, is to generate new neurons during the adult life of mammals, including … Continue Reading Researchers validate microglia role in reducing neurogenesis due to epileptic seizures.
Researchers identify how the blood-brain barrier is maintained to control ‘tight junction’ function.
It has long been known that the brain is protected from alterations elsewhere in the body by a highly regulated gateway known as the blood-brain barrier, which allows only selected … Continue Reading Researchers identify how the blood-brain barrier is maintained to control ‘tight junction’ function.
Epilepsy is a very prevalent neurological disorder. Approximately one-third of patients are resistant to currently available therapies. A team of researchers from the University of Bonn has discovered a new … Continue Reading Astrocytic ‘uncoupling’ identified and reversed in temporal lobe epilepsy.
Researchers from the University of Wisconsin have developed a unique model for learning more about the role of human astrocytes. The findings may lay a foundation for the treatment of … Continue Reading Researchers grow human astrocytes in situ for the first time for potential ALS cure.
